Definitions

  • the present invention relates to improvements made in electric signs bearing publicity, or any other information, with which an easier access is provided to the interior of the sign, so that a minimal number of workers without specific training may carry out maintenance tasks of the sign.
  • the improvements also allow use of continuous polycarbonate sheets of considerable length, preventing expansion problems which previously prevented use of very long sheets.
  • the improvements introduced in this invention consist of providing on the bottom of the sign structure and along its entire length a door which, upon being opened towards the inside of the sign, reveals a space sufficiently large for the worker to access the inside of the sign and comfortably carry out any maintenance tasks, so that no specifically skilled labourers are required for this task, as well as resulting in a considerable reduction of the time employed as no sign components need to be disassembled and assembled.
  • the other improvements introduced consist of providing, in the bottom bar which defined the lower edge of the sign, a set of small rollers which are free to rotate and which occupy the entire length of the sign, placed perpendicular to the polycarbonate sheet so that this sheet rests on them on its bottom edge. Due to these rollers the weight of the sheet does not hinder its thermal expansion as the rollers allow its displacement during expansion or contraction.
  • Figure 1 shows the bar based structure of a known electric sign, consisting of an bar (2) for attachment to the wall, and decorative bars (5) which conform the top and bottom longitudinal ends and on which are inserted the edges of a polycarbonate sheet (1) bearing the information or publicity.
  • One of the improvements of the invention consists in that on a lower area of the rear wall of the sign is provided a search door (4) formed from a bar as shown in figure 3, which occupies the entire length of the sign and which opens inwards in order to allow easy access to the sign interior, as shown in figure 2.
  • search door (4) may be shorter than the frill length of the sign, and several doors may even be provided which span the length of the sign.
  • the bar which forms search door (4) has a lower rounded edge (6) about which it may open as it is inserted in the corresponding complementary groove of bar (2).
  • Search door (4) is shaped along its entire top edge in the form of a catch (7) meant to lock search door (4) in its closed position by pressure, as this edge is inserted in a catch (7) in a complementary groove of bar (2), so that search door (4) can be opened simply by pushing it inwards until it is unlocked.
  • Polycarbonate sheet (1) is installed in the electric sign by means of its top and bottom edges which are inserted in decorative bars (5, 5'), the second improvement of the invention being based on incorporating a set of rollers (3) along the inside of lower bar (5), placed so that polycarbonate sheet (1) rests on them.
  • Rollers (3) may be made from any material and in any size considered suitable for their functionality, and are placed perpendicular with respect to the normal plane of polycarbonate sheet (1) so that they allow the latter to slide as it expands and contracts with ambient temperature.
  • any length of polycarbonate sheets (1) may be used without suffering from the problems which result from expansion in conventional signs.
